In uniform motion instantaneous velocity is equal to the

For uniform motion :

A particle is projected with a speed v and an angle theta to the horizontal. After a time t, the magnitude of the instantaneous velocity is equal to the magnitude of the average velocity from 0 to t. Find t.

A cockroach moves rectilinearly such that after sometime t_(0) let its (instantaneous) velocity be equal to its average velocity over that time. Referring to the S Delta t graph as shown in , for the motion of the cockroach, find the time t_(0) and the average velocity of the cockroach over the time t_(0) .

The instantaneous velocity of a particle is equal to time derivative of its position vector and the instantaneous acceleration is equal to time derivatives of its velocity vector. Therefore :

(A): Velocity-time graph for an object in uniform motion along a straight path is a straight line parallel to the time axis. (R ):In uniform motion of an object velocity increases as the square of time elapsed.

Assertion: Average speed of a particle in a given time interval is never less than the magnitude of the average velocity. Reason: The magnitude of the velocity (instantaneous velocity) of a particle is equal to its speed.

A particle is in uniform circular motion, then its velocity is perpendicular to

In uniform circular motion

The average velocity of a particle moving on a straight line is zero in a time interval. Assertion :- It is possible that the instantaneous acceleration is never zero in the interval. Reason :- It is possible that the instantaneous velocity is never zero in the interval.

If the object is moving with uniform velocity in a given interval of time, then the average speed and instantaneous velocity are equal, why?
